Replacement shields for all G-Force Force One or Pro Force One 2005/2010/2015 helmets. All G-FORCE Racing Gear shields are injection-molded in a specially designed mirror polished mold. This results in an optically correct molded shield. Other manufacturers cut their shields out of plastic and bend them over a form. This is a much cheaper process and does not produce an optically correct shield. G-Force thinks it is important that you see an undistorted view of your competition.
